The Bahrain bank merger between National Bank of Bahrain (NBB) and Bank of Bahrain and Kuwait (BBK) has moved into a decisive phase, with the two lenders now negotiating the terms of a tie-up that would create one of the largest banks in the kingdom. NBB submitted a formal merger proposal to BBK’s board on 26 April 2026, and after BBK reviewed it at a 5 May board meeting, the two sides opened talks on the exchange ratio and other definitive terms, according to disclosures filed with Bahrain Bourse.
If completed, the combination would bring together two of Bahrain’s oldest and most systemically important banks. Based on their most recent reported balance sheets, the merged entity would hold roughly USD 28bn in combined assets, giving it far greater scale to compete with regional heavyweights in Saudi Arabia and the UAE.
How the deal has progressed
The two banks first initiated a merger proposal in June 2024. Due diligence began in January 2026, and both sides have since described the process as advancing steadily. The April proposal and the subsequent start of negotiations mark the point at which a long-discussed idea turned into concrete deal-making on price and structure.
- June 2024: NBB and BBK initiate a merger proposal.
- January 2026: Due diligence process begins.
- 26 April 2026: NBB submits a formal proposal to BBK’s board.
- 5 May 2026: BBK reviews the proposal and negotiations on the exchange ratio commence.
Around the time the proposal was submitted, NBB shares closed at BHD 0.50 (about USD 1.32) and BBK shares at BHD 0.54 on Bahrain Bourse. The exchange ratio being negotiated will determine how BBK shareholders are compensated in the combined company, and it is the single most closely watched term of the deal.
Two pillars of Bahrain’s banking sector
NBB, licensed in 1957, is the kingdom’s oldest locally incorporated bank. Bahrain’s sovereign wealth fund, Mumtalakat Holding Company, holds a 49 percent stake in NBB, giving the state a direct interest in the outcome. BBK, established in 1971, counts the Bahraini government, Kuwaiti banks and investment companies, and the public among its shareholders.
The scale of the two institutions underlines why the merger matters. NBB’s assets grew 8 percent year on year to BHD 5.97bn (about USD 15.8bn) in the first half of 2025, while BBK’s assets stood at around BHD 4.6bn (about USD 12.2bn) at the end of September 2025. Combining the two would produce a lender with meaningfully deeper capital, a larger deposit base and a broader retail and corporate franchise.
A national priority
BBK Group chief executive Yaser Alsharifi has described the tie-up as a “national priority” with significant strategic value for the kingdom’s banking sector. Goldman Sachs has been appointed as financial adviser on the transaction. The deal is being closely tracked by the Central Bank of Bahrain, which would need to approve any final agreement, as well as by shareholders of both listed banks.
For Bahrain, consolidation is partly a response to a crowded banking market. The kingdom hosts a large number of retail and wholesale banks relative to its size, and policymakers have long viewed mergers as a route to stronger, better-capitalised institutions capable of absorbing shocks and funding larger deals. Banks also form a central pillar of Bahrain’s non-oil economy, which now accounts for the bulk of national output. Financial services remain one of the largest contributors to GDP, so a healthier, more competitive banking core carries weight well beyond the sector itself.
What it means and the outlook
A successful merger would reshape the competitive map of Bahraini finance and could prompt further consolidation among the kingdom’s mid-sized lenders. For customers and expatriates who rely on these banks for salaries, mortgages and everyday accounts, the immediate practical effects would come later, once integration begins. Those managing budgets and residency logistics in the kingdom can plan around a still-functioning system in the meantime, as covered in our cost of living in Bahrain 2026 guide and our Bahrain CPR and residency ID guide.
Reports indicate the merger remains on track for potential completion in 2026, though no binding timeline has been confirmed and much depends on the exchange ratio talks now under way. With regulatory approval and shareholder votes still ahead, the coming months will show whether Bahrain is on course to gain a new banking champion, or whether the terms prove harder to settle than the strategic logic suggests.
